| TRANSFORMER PART-TANK
JNL are engrossed in manufacturing, supplying and distributing a superior quality range of Tanks for Transformers. Only quality approved MS is used as raw material by us, which makes these tanks more durable and sturdy. Most modern welding equipment is used to ensure the quality of welding and joints.Customers can provide detailed tank drawings As in the following drawing for us to carry out customized production.
Tanks
- Single-phase transformers: Cylindrical, made from Cold Rolled and Hot Rolled Steel.
- Three-phase transformers: Rectangular in shape, made of Cold Rolled or Hot Rolled steel, with reinforcements capable of withstanding internal pressures resulting from temperature rise and mechanical stresses due to equipment installation and handling.
- Cold Rolled steel radiators are attached to the tank.
Scope of the offer:
Manufactured in compliance with applicable NTC and IEC standardsand/or individual customer specifications.
Ratings (kVA):
Three-phase: 30 kVA to 3150 kVA.
Basic Insulation Level:
Three-phase: Up to BIL 35 kV
| TRANSFORMER PART-RADIATOR
With the help of our advanced engineering skills, JNL are able to provide a superior range of Electric Transformer Radiators. Our all-welded steel construction radiators are manufactured in compliance with the international standards for quality. The compact and sleek design of our range allows the clients to install it in limited floor space. Clients can avail our range in various specifications as per their requirements.
Radiators
- The radiators are composed of a series of metal fins or copper tubes arranged together, which are typically connected to the cooling oil circuit of the transformer.
- Radiators are equipped in a transformer with the function of cooling the transformer oil through natural air or forced air flowing in these radiator fins
Scope of the offer:
Manufactured in compliance with applicable NTC and IEC standardsand/or individual customer specifications.
Ratings (kVA):
Single-phase: 10 kVA to 100 kVA
Three-phase: 30 kVA to 3150 kVA.
Basic Insulation Level:
Three-phase: Up to BIL 35 kV
| TRANSFORMER PART-CCA
Coils:
- Rectangular cross section and concentric copper or aluminum windings.
- Insulation: High-quality epoxy resin coated paper.
Cores:
- Shell Type or Core Type, wound with a back-to-back interleaving arrangement, step-lapped for easy assembly and disassembly without losing dimensional characteristics, thus ensuring very low levels of losses and excitation currents.
- Materials: Cold-rolled grain-oriented silicon electrical steel sheet with insulating coating on both sides, low core loss and high permeability.
Yoke clamps:
- Made of cold-rolled and hot-rolled steel, they clamp the core, with individual bolted caps that can be easily removed and disassembled for maintenance purposes.
- They ensure high resistance to short circuit mechanical stresses, with low noise levels and low excitation currents.
Scope of the offer:
Manufactured in compliance with applicable NTC and IEC standardsand/or individual customer specifications.
Ratings (kVA):
Single-phase: 10 kVA to 100 kVA
Three-phase: 30 kVA to 3150 kVA.
Basic Insulation Level:
Three-phase: Up to BIL 35 kV

Scope of the offer:
Manufactured in compliance with applicable NTC, IEC and ANSI standards and/or individual customer specifications.
Low-Low, Class 1.2 kV
Medium-Low, Class 15 kV
Ratings (kVA):
Three-phase: 15 kVA to 1500 kVA
Basic Insulation Level:
Three-phase: Up to BIL 60 kV
Oil-immersed transformer
Scope of the offer:
Manufactured in compliance with applicable NTC, IEC and ANSI standards and/or individual customer specifications.
Single-phase transformers may be manufactured with one or two high-voltage bushings to be connected in E1GrdY/E or E/E1GrdY configurations, where E is the phase-to-neutral voltage and E1 is the phase-to-phase voltage. Low voltage configurations are typically 2E/E or E/2E; the latter are usually used to form threephase banks. Switchable single-phase transformers are specially designed to operate at two different input voltages.
Three-phase transformer configuration is made in accordance with the connection required by the standard or by the customer; the most common types are Dy, Yd, Dd, Yy, Dz, Yz.
Ratings (kVA):
Single-phase: 10kVA to 100 kVA
Three-phase: 30 kVA to 1600 kVA
Basic Insulation Level:
Single phase: Up to BIL 35 kV
Three-phase: Up to BIL35 kV
